wish list fo the next yearwish list fo the next year
• Open Government Data as a Right
• More Schemas (Knowledge APIs) – keep it focused, let’s not try to boil the ocean
• Open Data as a Platform, Not a Commodity
• Massive Interconnection Between Open Data Sites
• Open Corporate Data (for and by Corporates)
• Standards (e.g. for catalog metadata) for Data Portals and Data Hubs
• Open Data for Growth – making clear the the connection
• Strong international norms for data inventories
• Organizational identifiers – Dunn & Bradstreet should be replaced with open data
• MiData – getting personal data out of corporates and government back into the hands of the people whose data it is

Il Trentino deve farsi protagonista del movimento Open Data in Italia e, nel 2012, avrà l'occasione di mettersi alla guida dell'avanguardia concentrata sulla creazione di SEMPLICI best practices per una semantica condivisa! (Linked open data for dummies: questa è la sfida.)
